WA4320-acn-e 如何由胖模式转成痩模式，需要文件吗，AC是WX3010

1.2  现网有AC的场景（命令行）

操作风险提示：AP胖切瘦有风险，操作不当或者意外断电会导致设备故障，操作需谨慎。当AC存在的场景下，我们推荐使用Ap-mode命令完成AP的Fat转Fit的切换，在AP上执行该命令前，必须确认AC上的bin文件版本配套一致以及AC侧配置并使能了Dhcp server。当执行完命令后，AP的flash会被格式化，然后重启获得ip地址后在AC上下载对应版本。可以Telnet或者Console登入到命令行进行操作，具体操作过程如下所示，

1.5  现网无AC同时AP本身有串口的场景（Bootrom）  

先通过console线进入bootrom菜单，具体的操作，参考《AP瘦切胖配置案例（Bootrom）》，需要把胖AP（ fat）版本换成瘦AP（fit）版本通过tftp服务器上传加载。

1.6  现网无AC同时AP本身没有串口的场景

WAP722E和WAP722没有console口，针对这种情况，不能使用ap-mode命令切换，一旦切换就无法现场恢复。建议此场景下，telnet到胖ap上后，删除flash里的app文件后上传新的bin文件，然后通过boot-loader指定启动文件后重启。如果dir发现flash里有startup.cfg的文件，建议删除后再执行reboot命令。因此在实际开局和维护时一定要格外注意。参考《现网无AC同时AP本身有串口的场景（命令行）》。
